4 Aana & 5 Aana House Design in Nepal: Layout, Floors, Vastu & Cost

Most Kathmandu homes are built on 4–5 aana plots. Learn what fits on each size — footprint after setbacks, ideal layouts floor by floor, Vastu placement and indicative costs.

The Standard Kathmandu Plot

If you are building in Kathmandu Valley, chances are your plot is 4 or 5 aana — the sweet spot between affordability and buildability. We design more homes on these sizes than any other. The good news: with smart planning, a 4 aana plot comfortably houses a modern family home. The catch: every foot matters, so the layout, structure and Vastu must be decided together, not patched later.

What You Actually Get to Build

  • 4 aana ≈ 1,369 sq ft plot. After typical municipal setbacks, the buildable footprint is roughly 700–900 sq ft per floor.
  • 5 aana ≈ 1,711 sq ft plot. Footprint roughly 900–1,100 sq ft per floor.
  • Setbacks depend on your road width and municipality — commonly about 5 ft from the road plus side/rear clearances. Confirm your ward's bylaws before designing.
  • Most families build 2.5 storeys (ground + first + half top floor), giving a total built-up area of about 1,800–2,300 sq ft on 4 aana and 2,300–2,900 sq ft on 5 aana.

Typical 4 Aana Layout (2.5 Storeys)

  • Ground floor: living room (north/east), kitchen + dining (kitchen in south-east), common bathroom (north-west), stairs to the south/west, and parking if required.
  • First floor: master bedroom (south-west), one or two more bedrooms, family space, attached + common bathrooms.
  • Top (half) floor: pooja room towards the north-east, laundry/store, and an open terrace draining north-east.

What 5 Aana Adds

  • A genuinely separate dining space and a larger kitchen.
  • Comfortable on-site parking without squeezing the entrance.
  • An extra bedroom or a proper home office per floor.
  • More breathing room to keep the Brahmasthan (centre) open and get light into every room.

Vastu on a Small Plot — What to Prioritise

  • Get the main entrance pada right for your facing direction — this costs nothing extra.
  • Kitchen in the south-east, master bedroom in the south-west, stairs to the south/west, pooja and open terrace towards the north-east.
  • Keep toilets to the north-west/west, out of the north-east and centre.
  • On tight plots, perfect Vastu everywhere is rarely possible — prioritise the entrance, kitchen, master bedroom and toilets, and handle the rest with remedies.

Indicative Cost (2082/83 BS)

  • At Rs. 2,600–3,800 per sq ft for an RCC frame house with standard finishing, a 2.5-storey home costs roughly Rs. 55–80 lakh on 4 aana and Rs. 65 lakh–1.1 crore on 5 aana, depending on specification.
  • Design, naksha pass, soil test and supervision are additional but small fractions of the total.
  • The only reliable number is a BOQ (bill of quantities) from your actual drawings — beware of per-sq-ft promises made before the design exists.

The Bottom Line

A 4 aana plot builds a comfortable 3-bedroom family home, and 5 aana adds genuine breathing room — if the layout, structure and Vastu are planned as one from day one. Confirm your setbacks first, prioritise the high-impact Vastu decisions, and budget from a real BOQ rather than a per-sq-ft guess. At VastuVeda Designs, 4–5 aana homes are our daily work: we can show you what your exact plot dimensions support before you commit to anything.

Frequently Asked Questions

A typical 2.5-storey house on 4 aana comfortably fits 3 bedrooms, a living room, kitchen-dining, 2–3 bathrooms, a pooja room and a terrace — about 1,800–2,300 sq ft of built-up area in total. The final count depends on your footprint after setbacks (typically 700–900 sq ft per floor) and how efficiently the stairs and circulation are planned. Adding a third full floor instead of a half floor increases rooms but also cost and structural requirements. A squarish plot builds more efficiently than a long, narrow one of the same area.
As an indicative range for 2082/83 BS, a 2.5-storey RCC house with standard finishing costs roughly Rs. 55–80 lakh on a 4 aana plot, at about Rs. 2,600–3,800 per sq ft of built-up area. Premium finishing pushes it higher. The plot size itself does not set the cost — the built-up area and specification do. Structure and basic finishing are fairly predictable, but tiles, kitchen, bathroom fittings and joinery swing budgets widely. The only dependable number is a bill of quantities (BOQ) prepared from your actual drawings by a licensed engineer, so treat any per-sq-ft quote given before the design exists as marketing, not budgeting.
The extra aana (≈342 sq ft) adds real comfort: a separate dining space, easier parking, an extra room per floor, and more freedom to keep the centre open and every room naturally lit. Whether it is worth the land price difference depends on your location. On 4 aana, design is an exercise in careful trade-offs; on 5 aana those trade-offs relax noticeably. If your family is growing, works from home, or wants comfortable on-site parking, the fifth aana usually pays for itself in liveability. But a well-designed 4 aana home beats a poorly-designed 5 aana one — the design quality matters more than the extra land.
Yes — prioritise the decisions with the biggest impact: correct entrance pada, kitchen in the south-east, master bedroom in the south-west, stairs to the south/west and toilets in the north-west. Minor compromises elsewhere can be handled with remedies. Perfect textbook Vastu assumes generous space; on a compact urban plot the art is prioritisation. The entrance, kitchen, master bedroom and toilets carry the most weight, and getting them right costs nothing extra at the design stage. Keeping the small central area free of toilets and heavy stairs, and the north-east corner light, preserves the essentials. This is exactly why Vastu should enter the design on day one rather than being checked at the end.
